C#でメニューを初めて使ってみた

メインメニューなるものを「C#によるプログラミングWindows上」本を見ながら作ってみました。

ホントにメニューのフォントやサイズを変えられるんだ。
なんかどろくさいけどｗ

「BigMenuItem」クラス

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing;

namespace ABCS.UserClass
{
    class BigMenuItem : MenuItem
    {
        public BigMenuItem(string strgText, EventHandler ehClick) : base(strgText, ehClick) { this.setInit(); }
        public BigMenuItem(string strgText) : base(strgText) { this.setInit(); }
        public BigMenuItem() : base() { this.setInit();  }

        private void setInit()
        {
            this.MeasureItem += this.ehOnMeasureItem;
            this.DrawItem += this.ehOnDrawItem;
            this.OwnerDraw = true;

        }

        private int iFontPointSuze_ = 16;
        public int iFontPointSize
        {
            get
            {
                return this.iFontPointSuze_;
            }
            set
            {
                this.iFontPointSuze_ = value;
            }
        }

        protected void ehOnMeasureItem(object sender, MeasureItemEventArgs e)
        {
            MenuItem mi = sender as MenuItem;
            if (mi != null)
            {
                Font font = new Font(mi.Text, iFontPointSize);

                StringFormat strgfmt = new StringFormat();
                strgfmt.HotkeyPrefix = System.Drawing.Text.HotkeyPrefix.Show;

                SizeF sizef = e.Graphics.MeasureString(mi.Text, font, 1000, strgfmt);

                e.ItemWidth = (int)Math.Ceiling(sizef.Width);
                e.ItemHeight = (int)Math.Ceiling(sizef.Height);

                e.ItemWidth += SystemInformation.MenuCheckSize.Width * e.ItemHeight / SystemInformation.MenuCheckSize.Height;

                e.ItemWidth -= SystemInformation.MenuCheckSize.Width;
            }

        }

        protected void ehOnDrawItem(object sender, DrawItemEventArgs e)
        {
            MenuItem mi = sender as MenuItem;
            if (mi != null)
            {
                Graphics grfx = e.Graphics;
                Brush brush;

                Font font = new Font(mi.Text, iFontPointSize);
                StringFormat strgfmt = new StringFormat();
                strgfmt.HotkeyPrefix = System.Drawing.Text.HotkeyPrefix.Show;

                Rectangle rectCheck = e.Bounds;
                rectCheck.Width = SystemInformation.MenuCheckSize.Width * rectCheck.Height / SystemInformation.MenuCheckSize.Height;

                Rectangle rectText = e.Bounds;
                rectText.X += rectCheck.Width;

                e.DrawBackground();
                if ((e.State & DrawItemState.Checked) != 0)
                {
                    ControlPaint.DrawMenuGlyph(grfx, rectCheck, MenuGlyph.Bullet);
                }

                if ((e.State & DrawItemState.Selected) != 0)
                {
                    brush = SystemBrushes.HighlightText;
                }
                else
                {
                    brush = SystemBrushes.ControlText;
                }

                grfx.DrawString(mi.Text, font, brush, rectText, strgfmt);
            }
        }

    }
}

「BigCheckMenuItem」クラス

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ABCS.UserClass
{
    class BigCheckMenuItem : BigMenuItem
    {
        public BigCheckMenuItem(string strgText) : base(strgText) { this.setInit(); }

        protected void setInit()
        {
            this.Click += ehOnClick;
        }

        protected void ehOnClick(object sender, EventArgs e)
        {
            this.Checked = !this.Checked;
        }

    }
}

メインメニューを作る、makeMainMenu()関数

        private void makeMainMenu()
        {
            string ret = "";
            Menu = new MainMenu();
            
            //「ファイル」メニュー
            Menu.MenuItems.Add("ファイル");
            Menu.MenuItems[0].MenuItems.Add(new BigMenuItem("印刷"));

            //「ソフトキーボード」メニュー
            Menu.MenuItems.Add("ソフトキーボード");

            BigMenuItem[] bmi = new BigMenuItem[4];

            bmi[0] = new BigCheckMenuItem("ソーシャルIME予測変換");
            settingsSingleton.getValue(settingsSingleton.KeyUsePredictSocialIME, out ret);
            if (settingsSingleton.TRUE.Equals(ret))
                bmi[0].Checked = true;
            bmi[0].Click += this.saveSettingSocialIMEPredict;
            this.SocialIMEPredictMenuItem = bmi[0];

            ret = "";
            bmi[1] = new BigCheckMenuItem("ソーシャルIME通常変換");
            settingsSingleton.getValue(settingsSingleton.KeyUseNormalSocialIME, out ret);
            if (settingsSingleton.TRUE.Equals(ret))
                bmi[1].Checked = true;
            bmi[1].Click += this.saveSettingSocialIMENormal;
            this.SocialIMENormalMenuItem = bmi[1];

            ret = "";
            bmi[2] = new BigCheckMenuItem("VJE予測変換");
            settingsSingleton.getValue(settingsSingleton.KeyUsePredictVJE, out ret);
            if (settingsSingleton.TRUE.Equals(ret))
                bmi[2].Checked = true;
            bmi[2].Click += this.saveSettingVJEPredict;
            this.VJEPredictMenuItem = bmi[2];

            ret = "";
            bmi[3] = new BigCheckMenuItem("VJE通常変換");
            settingsSingleton.getValue(settingsSingleton.KeyUseNormalVJE, out ret);
            if (settingsSingleton.TRUE.Equals(ret))
                bmi[3].Checked = true;
            bmi[3].Click += this.saveSettingVJENormal;
            this.VJEPredictMenuItem = bmi[3];

            Menu.MenuItems[1].MenuItems.AddRange(bmi);
        }
